Method new

datafusion/datasource/src/table_schema.rs:119–127

Create a new TableSchema from a file schema and partition columns. The table schema is automatically computed by appending the partition columns to the file schema. You should prefer calling this method over chaining [`TableSchema::from_file_schema`] and [`TableSchema::with_table_partition_cols`] if you have both the file schema and partition columns available at construction time since it avoid

(file_schema: SchemaRef, table_partition_cols: Vec<FieldRef>)

    /// assert_eq!(table_schema.table_schema().fields().len(), 4);
    /// ```
    pub fn new(file_schema: SchemaRef, table_partition_cols: Vec<FieldRef>) -> Self {
        let mut builder = SchemaBuilder::from(file_schema.as_ref());
        builder.extend(table_partition_cols.iter().cloned());
        Self {
            file_schema,
            table_partition_cols: Arc::new(table_partition_cols),
            table_schema: Arc::new(builder.finish()),
        }
    }

    /// Create a new TableSchema with no partition columns.
